Secrets of the Universe: Journey to the DISCOVERY of TERRIFYING Phantom Stars - Space Documentary

🌍 Discover the hidden wonders of the universe, a realm where mysteries abound and every discovery opens the door to new questions. In this video, we dive into the immensity of space to explore the stars of the universe, those luminous stars that have fascinated mankind since the dawn of time. Among these stars, brown dwarfs occupy a special place, floating on the border between giant planets and less massive stars, they represent a fascinating subject of study for astronomers the world over.
The stars of the universe are a vast subject of study, covering many different aspects of astrophysics. From the main sequence to supernovae, pulsars and quasars, the universe is a theater of cosmic operations in which each star plays a crucial role. Brown dwarfs, often dubbed "failed stars", fall outside the traditional category of stars because they lack the mass necessary to initiate nuclear reactions in their core. However, their study offers unique insights into the formation of stellar systems and the classification of celestial bodies.
The universe is full of mysteries waiting to be explored. From supermassive black holes, silent guardians of galaxies, to distant exoplanets, fertile ground for the search for signs of extraterrestrial life, each discovery brings us a little closer to understanding our place in the universe. Technological advances, such as the latest generation of space telescopes and robotic exploration missions, have considerably broadened our horizon of knowledge, revealing cosmic phenomena previously invisible to the naked eye or even unimaginable.

💥The Brown Dwarfs:
- In the 1980s, the theory of potential brown dwarfs proved relevant enough for astronomers to systematically include them in their long list of objects to be detected. However, these dark objects emit only weak radiation, which is mainly detectable in the infrared range. Unfortunately, for researchers in search of a major discovery, the detection equipment of the period was not sensitive enough to bring these mysterious objects to light. It wasn't until January 1994 and the arrival of more powerful equipment that the first brown dwarfs were finally observed, confirming this theory. Three astronomers from the Canary Islands Institute of Astrophysics, using their telescope at Teide on the island of Tenerife, succeeded in capturing one of these extremely discreet stars for the very first time. This is Teide 1: the first brown dwarf to emerge from the shadows, with a mass estimated at between 40 and 60 times that of Jupiter. Located some 430 light-years from Earth in the constellation Taurus, it was hiding in the open Pleiades cluster. Its cold nature was confirmed the following year, in 1995, by the William-Herschel optical telescope on the island of La Palma.
The following months saw the discovery of Gliese 229B, a brown dwarf orbiting the star Gliese 229A. The observation of this object, about 20 to 50 times the mass of Jupiter, was made possible by the use of a coronagraph, an instrument that artificially dims the brightness of its host star. New discoveries of brown dwarfs soon followed. Many of them were detected near our solar system, where they turned out to be quite old and faint, as well as at the heart of distant clusters of young stars, where they were still relatively bright.
Brown dwarfs are classified according to their spectral type. Unlike main-sequence stars, whose energy is derived from nuclear reactions, the energy of brown dwarfs derives from their gravitational energy, converted into internal energy by contraction. The hottest of these, with temperatures close to 2,500°C, are M6.5 dwarfs, as are very low-mass stars such as red dwarfs.

Awesome and can’t wait for the next video ❤😊❤

[@other-terrestriallifeform1851]

This is a highly informative video and worthy of the scientific spirit inspiring it! "KUDOS"

[@JimKrause1975]

I love it!

❤❤

[@donnysandley4649]

I totally got schooled on what I thought I knew about dwarf Stars 🤩

[@nataliep6385]

I wish you would add english subtitles that isn't auto-generated. It gets pretty annoying in the long run :(

[@ashleyobrien4937]

pity they had totally ruin it with that ridiculous A.I. voice...ugh ! who talks like that ?

[@666evo666]

You are so wrong, the AI voice is perfect, no bias in the voice, no overly opinionated voice overs, no emotional discharge just raw science facts. The voice is the very reason why I can listen to this channel over and over. There is many other real humans on the internet doing narration if you prefer just listen to those channels. Ruined? nope only a human can do that.
